Planting & Care

Sow Sulphur Cosmos seeds directly outdoors after the last frost date, or start indoors 4-6 weeks before the last frost for earlier blooms. Press seeds lightly into the soil; they need light to germinate, so do not cover deeply. Keep the soil moist until germination, which typically occurs in 7-21 days at 70-75°F (21-24°C). Once seedlings are a few inches tall, thin them to the recommended spacing to allow good air circulation.

These cosmos are relatively carefree. Water regularly during dry spells, but avoid overwatering as they prefer well-drained soil. Deadhead spent flowers to encourage continued blooming. Fertilize sparingly; too much nitrogen can lead to lush foliage at the expense of flowers. Taller varieties may benefit from staking in windy areas. At the end of the season, allow some flowers to go to seed to self-sow for next year.
